Letters Patent No. 96,177, dated October 26, 1869;

IMPROVEMENT IN COTTON-SEED HULLING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the name- To all whom it may concern Be it known that I, FRANK A.WELLS, of Memphis,

in the county of Shelby, and State of Tennessee, have invented a new and improved Cotton-Seed Huller; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to Make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

The object of this invention is to provide'a cottonseed huller, more eflicient in operation, less liable to clog or be damaged by foul or hard substances, and better adapted for adjustment of the cutters of the concave shell than the machines now in use.

It is also intended to provide a more economical arrangement of the cutters, in respect of grinding them.

Figure 1 represents a transverse sectional elevation of my improved machine, and

Figure 2 represents a plan'view of the same. I Similar letters of reference indicate corresponding parts.

A represents the revolving cylinder, the cutters B of which consist of steel or chilled plates, concaved on both sides, and ground square on the edges, and placed in suitable recesses in the cylinder, pitched at the' proper angle to give the best results in action with the cutters of the shell, and adapted for turning the said cutters B, so as to use all the corners thereof successively, as they become worn.

The concave shell is composed of knives C and dividing-plates D.

The dividing-plates are arranged in a circular clamp, E, and in circular supports. in the side-frames of the machine.

These end supports F are provided with set-screws G, screwing against both the outer and inner edges of the cutters, for adjusting them to or from the cylinder, or the cutters thereof.

The cutters of the concave are made with edges at changed, to utilize all the corners as cutting-edges, and they are set at an angle with the radial lines of the cylinder, to present the corners more acutely in the direction of the cutters of the cylinder.

The cylinder is revolved in the direction indicated Q by the arrow, and thereby the work is much more uniformly accomplished, as all the seeds are brought between the edges of the cutters, whereas, if revolved the other way, many of the seeds would be crowded into the lowest part of the recesses. at therear of the cutters of the cylinder, and thereby escape the actions of the cutters, also clogging the machine to a considerable extent.

Another important advantage of running in this direction is, that heavy and hard substances, such as stones, iron, 8m, will not be carried in between the cylinder and the concave, unless quite small, but will remain on the top of the cylinder, in front of the concave, from where they may be removed readily.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent 1. The cylinder A, having knives B, shaped and ape plied as specified, in combination with the correspondin g knives O, of the concave shell, all operating together, substantially in the manncrdesoribed.

2. The combination of revolving knives B with cutters 0, arranged at a pitch below the centre of the cylinder, and having an independent radial adjustment, by means of setescrews or their equivalents, substantially as set forth.

3. The improved concave clamp E, provided with means for the separate adjustment of each squareended tool, with its cutting-edge at a pitch'below a radial line,and removable at the extremities of the concave, all as shown and described.
